CAR-COUPLING. J a

SPECIFICATION forming part of Letters Patent No. 225,040, dated March 2,1880,

i Application filed January 20, 1880.

To all whom tt may concern Be it known that I, JOSHUA D. AYoooK, ofDeetsville, in the county of Elmore and State of Alabama, have inventedcertain new and useful Improvements in Oar-Couplings; and I do herebydeclare the following to be a full,

clear, and exact description of the same, reference being made to theaccompanying drawin gs, forming a part of this specification, and inwhich- Figure 1 represents a front view of my improved coupler; Fig. 2,a top or plan view of the same; Fig. 3, a detail sectional view; Figs. 4and 5, side views of difierent forms of coupling-hooks.

My invention relates to certain new and useful improvements in the classof couplers and the invention consists in a novel construction,combination, and arrangement of parts, all as will he hereinafter fullydescribed, and specifically pointed out in the claims.

To enable others skilled in the art to which my invention is most nearlyconnected to make and use the same, I will now proceed to describe itsconstruction and operation.

In the drawings, A represents the front or rear portion of a car towhich my improvements are applied.

B represents the usual draw-head, provided with a triangular recess, 1),for the reception of the head of the coupling-bar.

O G represent the transverse lockingbars, provided on their upper faceswith rack-bars .c 0, into which mesh pinions D D, mounted on shafts (1cl, and operated by cranks dd, mounted or secured on the ends of saidshafts.

E represents an inclosed coiled spring, con nected at one end to one ofthe shafts of the pinions D, and its other end secured in the casing,whereby turning said pinions to move the locking-bars transverselyoutward to re lease the coupling-bar will wind up the spring, so thatthe locking-bars will always be auto matically returned to theiroriginal or lock position when not secured in an unlocked position bydevices hereinafter described.

F represents a transverse bar, connected at one end to the inner end ofone of the locking-bars E, said bar passing through a guide, G, providedwith'a friction-roller, g, bearing against the upper surface of the bar.The

bar F is also provided, near its outer end, with a rack-bar, f, intowhich one of the pinions D meshes, whereby turning either one of saidpinions will, through the medium of said rackbar F, simultaneously move-both of the lookingbars toward or from each other, as desired.

(0 represents a pivoted catch or pawl for engaging with the teeth of oneof the rack-bars c, for securing the locking-bars in an unlockedposition when desired.

The bar F is provided with a lug or pin,f, with which the lower end of apivot-ed lever, H, engages, and through the medium of which the lockingbars can be operated from theplatforms of the car or said lever can beextended up far enough to be operated from the top of the cars, saidlever being provided with a lug or pin, it, with which a catch, h,engages for securing the lockbars in an unlocked position. 1

I I represent two forms of coupling-bars, one of said bars, I, beingadapted for cars of different height, and the other bar, I, for cars ofthe same height.

The operation of my improved car-coupler is as follows: When it isdesired to uncouple or couple the cars the operator turns one of thecranks d from the side of the car, or the lever H from the platformortop of the car, and thus, through the medium of the rack-bars andpinions, nioving both of the locking-bars simultaneously outward, thuspermitting the ready withdrawal or insertion of the locking-bars, saidlocking-bars being returned to their original or looking position by thespring E.

I am aware that similar locking-bars, open ated through the medium oflevers and springs, are common in car-couplings, and such I do not wishto be understood as claiming, broadly, as of my invention; but, 7

. Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a car-coupling, the combination of the transverse locking-bars O0, provided with the rack-bars c c, pinions D D, intermediate connectingrack-bar, F f, and operating mechanism, substantially as and for thepurpose here in shown and described.

2. In a car-coupling, the combination of the locking-bars O 0, providedwith the rack-bars In testimony that I claim the foregoing as c c,pinions D D, intermediate connecting rackmy own lllYGIlfilOH 1 affix mysignature in pres bar, Ff, having lug or pinf, pivoted lever H, I enceof two witnesses.
